Okular always amazes me as an app, whose function you would think would be small enough to be unimpressive, and yet... I am always surprised by the great features I keep finding hidden away (like recently discovering it can open .pptx powerpoint files?!!)

Apart from the printing issue, it would be really great if we could have more advanced pdf features such as annotations to the file that would show up in all viewers and filling forms, etc. Overall though, Okular rocks!
